Capacitors and dialectrics

  1. Feb 26, 2006 #1
    Silly question, but I can't find the answer anywhere in my notes.

    When you have a capacitor with two parallel slabs of dialectric (equal thickness, different dialectric constants) in between the plates of a capacitor, would you find the capacitance by linear superposition (I wouldn't have thought so), or by an average dialectric constant?

    As I say it seems a little trivial, but I can't find the answer in either my notes or my textbook!

    Thanks guys

    consider then as two capacitors in series, both having half thickness, with different dielectric constants.
